Image Sprites
Image sprites are a web development technique that combines multiple small images into a single larger image file. This reduces the number of HTTP requests needed to load a webpage, as the browser downloads one sprite sheet instead of many individual images. Developers then use CSS to display specific portions of the sprite as needed, improving performance and load times.
Developers should use image sprites to optimize websites with many small images, such as icons, buttons, or UI elements, especially in performance-critical applications like e-commerce sites or mobile web apps. This technique is particularly valuable for reducing latency on slower connections and improving user experience by minimizing visual loading delays. It's a standard practice in front-end optimization to enhance page speed and reduce server load.
